Machine Lubricant Analyst
MLA II
Advanced oil analysis training for reliability, lubrication and condition monitoring professionals who need to diagnose lubricant degradation, contamination and abnormal machinery wear and translate laboratory results into corrective actions.
Move from Oil Test Results to Advanced Machinery Diagnosis
ORBITLINE Machine Lubricant Analyst II training develops advanced practical skills in lubricant-analysis-based machinery condition monitoring.
The course moves beyond basic lubricant knowledge and focuses on obtaining representative oil samples, interpreting lubricant health, identifying contamination problems and recognizing abnormal machine wear.
Participants learn how oil-analysis results such as viscosity, acid number, base number, FTIR, particle count, water, elemental spectroscopy and wear debris can be combined with machine operating information to determine the most probable cause of abnormal condition.
The objective is not only to identify an abnormal laboratory result, but to understand what it means, determine the likely failure mechanism and recommend an appropriate corrective action.
